Vicious. Violent. Vichyssoise. V-words are cranky and powerful. Vindictive if you do not vote on their movies. Velvety smooth if you do. Verily, like unto Barry White himself.

[EDIT: Poll closed! Virgins From Hell ran away with the poll, at 5 votes. Four movies in distant second with one each (Vampire Assassin, Vampire Circus, Vampires: the Turning, Varan the Unbelievable).]
